I am looking for a good protein powder to add to shakes that is vegetarian. Does anyone have any suggestions?

I highly recommend Vega or other hemp based protein powders. There are two vega ones, a smoothie infusion meant to be added to fruit smoothies and a meal replacement one (chocolate flavor is best).

I like Hemp Protein Powder too, which I get from Amazon.com
I can't do Whey Powder since I am lactose intolerant.
Tastes good too with soy milk and some wheat germ, ground flax seed and a banana in my Magic Bullet.
I look forward to one every morning.

I like the ones by Naturade. I get it at Whole Foods.
